95 4.0 Unable to start - RayJamm
My jeep was parked one morning and in the afternoon it would not start, checked for spark and there isn't one. The commonest problem I've seen with these is the crank sensor although this did seem a bit all of a sudden as there was now warning or other problems leading up to it. fuel pump primes and engine turns over fine.

I read somewhere that you can get the fault codes on your dash but not sure any help would be appreciated. I have checked relay's fuses and ordinary stuff.

Please help
Cheers

Hi
Turning the ignition on and off 3 times ending with on should pull up the codes. However can you tell me does all your gauges work, Fuel level, battery and so on? if no unplug the crank sensor turn the ignition back on again and if they then work it's a good sign it's the crank sensor at fault.

Hi Merlin, just looked up the codes and the 11 sounds like the problem as the other codes are ones I've created in diagnoses. where ndo I find the sensor and are they difficult to change as this is an auto and I can't move it without huge charges.

thanks

On the manual engines the sensor is above the front propshaft in the bellhousing as it takes a reading off the flywheel. Very common problem. If the sensor is OK when you crank the engine the ecu will know that the engine is rotating and switch on the fuelpump, so listen for the pump when cranking engine.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
